The purpose of this study is to understand the relationship between emotional labor, job burnout, and life satisfaction for art psychology counselors. The subjects were 225 art psychology counselors in ◯◯ City. As for the methods used, frequency analysis, reliability analysis, and correlation analysis were applied using SPSS 22.0, and multiple regression analysis was applied to causal relationships between variables. As a result of examining the effect on life satisfaction of emotional labor by art psychology counselors, surface behavior had a significant negative effect, while inner behavior also had a negative effect. Emotional exhaustion and a self-achievement decrease, which are sub-factors of job burnout for art psychology counselors, had a negative (-) effect on life satisfaction. This means that the lower the surface behavior of emotional labor by an art psychology counselor, the higher the inner behavior, and the lower the emotional exhaustion of job burnout and the lower the factor of self-achievement, the higher the life satisfaction. This study is considered to be basic data for the preparation of measures to reduce psychological burnout in art psychology counselors and can improve resilience in adaptation to the teaching profession.

This study was performed in oder to investigate to dietary behavior, perceived stress and their correlations of University students. The number of subjects was 549 and the results of this study are as followed: Only 13.9% of students-20% of male students, 10% of female students-exercise regularly. Regular exercise and health condition had no statistical relationship in this study. 83.9% of subjects had experience of alcohol drinking (19.4% of male students, 7.3% of female students). Many students replied that they drink alcohol 1∼2 times per a week. 24.4% of students-only 2.6% of female students-were smoking and great number of smokers were drinking also. The BMI of 46.7% of subjects were in normal range. 48.2% were in under weighted and 5.1% were in over weighted or obesity. The stress factor of University students were analyzed into 12. Inner stress factors like as identity, coursework, friendship, health problem were more potent in female students than male. Among the health related habits, disease itself had a great effect on many stress factors but regular exercise had a little.

Concrete-filled tubes (CFT), formed by an outer steel tube filled with plain or reinforced concrete inside, have been increasingly used these recent decades as columns or beam-columns, especially for tall buildings in seismic areas due to their excellent structural response. This improved behavior is derived from the effect of confinement provided by the tube, since the compressive strength of concrete increases when being subjected to hydrostatic pressure. In circular CFTs under compression, the whole tube is uniformly tensioned due to the radial expansion of concrete. Contrarily, in rectangular and square-shaped CFTs, the lateral flanges become subjected to in-plane bending derived from this volumetric expansion, and this fact implies a reduction of the confinement effect of the core. This study presents a numerical analysis of different configurations of CFT stub columns with inner stiffening plates, limited to the study of the influence of these plates on the compressive behavior without eccentricity. The final purpose is to evaluate the efficiency in terms of strength and ductility of introducing stiffeners into circular and square CFT sections under large deformation axial loading.

The purpose of this study was to obtain strategies for more effective management of family restaurants. A quantitative methodology was used to obtain the results. A questionnaire was designed to elucidate consumer dining patterns, as well as the factors that are important for consumers satisfaction in terms of the foodservice quality. The questionnaires were used to gather information from consumers at family restaurants and were then analyzed and evaluated. The results of this study indicated that there were important factors related to consumer satisfaction and the service aspects of family restaurants. As the results of empirical analysis, service quality factors in family restaurants were categorized into four factors such as inner shape of food, outer shape of food, facilities and service factors respectively. The analysis showed statistically significant difference at the 5% significance level in outer shape of food, facilities and service factors. These results will be used to assist in menu planning and quality reforms in the foodservice industry.

This study presents the behavior of unsteady saline wedge in which it is examined velocity profile variations at the lower layer (inner wedge) and wedge tip responses to a tidal action in a rectangular open channel. Unsteady saline wedge has just tidal excursions corresponding to tidal amplitudes at the river mouth, although two wedge tips in flood and ebb tide remarkably have different shapes. Maximum velocities at the lower layer appear immediately from high water to low water level (or low to high water). Numerical computation results obtained by only just interfacial friction factor at the steady state show satisfactory agreements with experimental data. However, the numerical model on one-demensional two-layer flor still has some problems to date.

Compression ring is a part of LNG storage tank. The main function of the compression ring is connected the roof plate with concrete side wall. End of its one side is embedded in the side concrete wall and the other's connected with the roof plate by welding. It is designed to support stably for all the loads such as self weight of steel roof, inner pressure and concrete weight. We fulfill the FEM analysis to analysis the compression ring behavior during construction. Also we studied the effect of the change of design variables. On the basis of the results, we could introduce a more reasonable design method for compression ring.

Semi-solid forming process has some advantages such as successful manufacturing of high quality components with less inner defects suitable for less machining high productivity and energy-saving effect. the thixotropic behavior(solid-like in the unperturbed state and liquid-like during shearing) has been the basis for the semi-solid forming process. The main focus of this article is the investigation of the effect of T6 heat treatment and alloying elements on the mechanical properties in the semi-solid formed products using thixotropic hypoeutectic (A357 and ALTHIX 86S) and hypereutectic(A390) materials. The new methods to produce semi-solid formed components with high quality are also proposed and discussed in terms of a die design and the development of a lubricant.

The fatigue test under the constant amplitude repeated loading is performed to investigate the fatigue behavior of the Torque Shear type high tension bolted joint which is able to manage the axial force uniformly. From the test results, it's known that the reduction of the axial force of T/S bolt followed by the elasped time is similar to that of the high tension bolts. The difference of relaxation is not occurred according to the position of bolts, the size of the introduced axial force but the effect of the variation of temperature is large. In the reduction of the axial force followed by the cumulation of the fatigue load, the outer bolt is larger than the inner bolt. This result depends on the difference in the distribution of the non-slip zone. The variation of the surface roughness affects the slip and the reduction of the anal force.

To improve the luminance and efficiency of AC PDP, the effects of a square pulse applied to the address electrode during a sustain-period is investigated. Through this experiment, we confirmed the improvement of luminance and efficiency. We performed the temporal behavior measurement for the light emitted from AC PDP at floating state of the address electrode and at various auxiliary voltages (including ground state) applied to the address electrode using the scanned point detecting system. In the case of using an auxiliary voltage pulse, emission starts at the inner edges of the anode and cathode simultaneously. Also, we obtained the larger two discharge volumes compared with the normal sustain discharge where address electrode is floated.

Performed here is an assessment study for deterministic fracture mechanics analysis of a pressurized thermal shock(PTS). The PTS event means an event or transient in pressurized water reactors(PWRs) causing severe overcooling(thermal shock) concurrent with or followed by significant pressure in the reactor vessel. The problems consisting of two transients and 10 cracks are solved and maximum stress intensity factors and maximum allowable nil-ductility reference temperatures are calculated. Their results are compared each other to address the general characteristics between transients, crack types and analysis methods. The effects of elastic-plastic material behavior and clad coating on the inner surface are explored.
